The focus of my position is to conduct applied research and to develop nutrient and lime recommendations that improve nutrient use efficiency by large acreage crops grown in Oregon. The crops of primary focus are on grass grown for seed, cereals, and potatoes, with a secondary focus on minor crops (other seed crops, peppermint, forages, vegetables, berries, Christmas trees, etc.).
My research program is focused on developing soil fertility research efforts that are statistically sound and address current soil fertility needs in Oregon large acreage field crops. Research interests include fertilizer response, nitrogen mineralization, acidificaiton caused by nitrogen fertilizers, lime response, plant nutrient uptake, and soil nutrient dynamics.
